DX Engineering Heavy-Duty Saddle Clamps
Our tradition of continuous innovation was evident with the introduction of the DX Engineering Heavy-Duty Saddle Clamp line. DX Engineering set new standards over a decade ago with the introduction of the industry's best clamps for mounting antennas and element tubing. Featuring superior gripping power, our new Heavy-Duty Saddle Clamps are available in six different sizes, to fit tubing with Outside Diameter (OD) inch sizes of 0.75, 1.00, 1.25, 1.50, 1.75, and 2.00. Commercial and industrial engineers and installation technicians all over the world have discovered a diverse range of applications for DX Engineering Heavy Duty Saddle Clamps. DX Engineering Heavy Duty Saddle Clamps are designed to be used where maximum torque handling is required on aluminum, steel or stainless steel tubing. Conceived of by builders of large and heavy Yagi antennas and Log Periodic arrays, these clamps are made in sizes that securely fit the outside diameter of tubing for mounting to a flat plate or surface. Their wide gripping surface equals superior clamping power! Perfect for antenna construction and mounting, or wherever standard U-bolt saddle clamps and other torque-control products have proven inadequate, our Heavy Duty Saddle Clamps provide excellent grip on booms, masts and element tubing. Unlike stamped or machined-type clamps, Heavy Duty Saddle Clamps are cast from a rugged aluminum alloy that grips tubing with a special textured surface and are sized for an incredibly secure fit that resists torque, wind and weather. Heavy Duty Saddle Clamps include two cast aluminum saddles (two halves) and a stainless steel reinforcement plate for high strength and superior corrosion resistance. Due to the wide diversity of clamping applications where Heavy Duty clamps are beneficial, mounting hardware is NOT included. However, a complete line of Armor-Coated and Stainless Steel Hex Bolt Hardware Sets are available for top performance in most mounting applications. Typical Heavy Duty clamp mounting applications on a 1/4 in. plate require a minimum length bolt set, as indicated in the chart, linked in "More Detail…," and displayed in the "Required Parts" tab. For larger tubing attachment applications with ultimate gripping strength, DX Engineering Super Duty Saddle clamps are also available for 2.0, 2.5 and 3.0 in. O.D. sizes. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. Plan your next project with the best clamps available... period. DX Engineering Heavy Duty Saddle Clamps are ready to provide superior performance for your antenna, mast or other tubing mounting application.

DX Engineering Aluminum Tubing
DX Engineering High-Strength Aluminum Tubes are ideal for your antenna building projects. It is made available in sizes that fit into and over the next, with close tolerances specifically designed for strength when joined and overlapping only by a few to several inches, to build Yagi, Moxon or vertical antenna elements. NOTE: This tubing is NOT intended for each size to telescope completely into the full length of the next; it cannot be used for telescopic mast building. DX Engineering aluminum tubing is manufactured to very close tolerances. This provides the greatest amount of surface contact between nesting tubes for mechanical and electrical stability. Due to the close tolerance, any burrs, dirt, grit or other foreign material, as well as dents, dings and unseen bending or crushing suffered during shipment will cause binding that prevents this aluminum tubing from fully nesting. 6063-T832 seamless drawn aluminum tubing is available in 3, 6 and 12 ft. lengths. 6063-T832 tubing provides good resistance to general corrosion, including stress corrosion cracking, and an excellent surface appearance. Use a series of 3 ft. lengths to build an element that tapers more quickly for lower wind-resistance applications. Use a series of 6 ft. lengths to make an element that tapers more slowly for greater strength and bandwidth. The 12 ft. lengths are great for HF Yagi construction. Most sizes (except 12 ft.) are available slit on one end for use with DX Engineering stainless steel element clamps. If un-slit ends are required for your applications, merely insert the slit end into the next larger size in the stack and use your own attachment method. 6063-T832 tubing features a 0.058 in. wall thickness and is available in 1/8 in. increments from 3/8 in. to 2-1/8 in. O.D. 3003-H14 drawn aluminum tubing features a 0.035 inch wall thickness and a 1/4 inch outside diameter. Each piece is supplied with non slit ends and is available in both 3 foot and 6 foot lengths, making them ideal for your antenna building projects. If your setup requires maximum strength at very long assembly lengths, then choose DX Engineering 6061-T8 tubing. This heavy-duty version features a 0.120 in. wall thickness and is available in 1/4 in. increments from 1-1/2 in. to 3 in. O.D. Packaged shipments of 6 ft. tubing have oversize shipping fees, regardless of the number of 6 ft. pieces. Therefore, order more 6 ft. pieces to spread oversize fees over more tubing for a more cost effective shipment. Tubing that is 12 ft. long MUST be shipped by truck freight. If you need many pieces of the same size in a 12 ft. tube length, then buying DX Engineering High-Strength Aluminum Tubing Bundles (elsewhere in our catalog) maximizes the economy of scale for your shipping costs. NOTE: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. Order DX Engineering High-Strength Aluminum Tubing here.
